Finally, a market that made sense! Jim Cramer loves when the market makes sense, because it gives him the ability to get creative and make judgments that can reap some serious rewards for investors.

What does Cramer mean when he refers to a market that makes sense?

"How about the fact that the slowing growth of the global economy and the negative manufacturing data we are seeing in this country have caused our interest rates to remain low—very logical," the "Mad Money" host said.

Cramer considers this data to be logical, because when rates are low then housing becomes more affordable. When housing is more affordable, then people will switch from renting to actual home buying.

This information, combined with the fact that banks are now willing to lend more with less of a payment, has spurred a mini-boom in housing. No wonder the homebuilder confidence is at a 10-year high.

Cramer has known for a while that this was bound to happen because the U.S. is finally back into household-formation mode. For many years after the Great Recession, young people either lived with their parents or family members. However, the data now shows that young families are buying their own homes.

"So, again, in a market that make sense, you can actually buy the stocks of the homebuilders and expect to make money," Cramer said.

Cramer's top pick was D.R. Horton, which is up 23 percent for the year. He has also recommended Toll Brothers and Lennar relentlessly, and they just broke through to levels that would be insane without this plunge in rates.

"What is extraordinary to me is that this move is happening right under the noses of people who should know better, but they keep waiting to get their signal from the Federal Reserve. You don't do that if you're a serious investor," Cramer added. (Tweet This)

That means investors should tune out the Fed talk and do the homework to figure out what stocks do better in the current environment. Cramer's answer? The homebuilders.

However, the upside is not just limited to homebuilders, as once you build a house it must be filled with goods. That brought Cramer to Web-based opportunities such as Wayfair and Amazon.

Cramer was not surprised by the New York Times article exposing Amazon's working conditions and thinks it isn't really important to the stock. Especially since the information recalled much of the information revealed by CNBC's David Faber in 2014 in a documentary entitled "Amazon Rising."
